Kinesis Advantage2 Quiet LF Ergonomic Keyboard (KB600LFQ)

I received the keyboard after waiting for weeks, and the package is missing the hands rest cushions... Disappointing...

TL:DR the Kinesis Advantage 2 LF (KB600LFQ) is a phenomenal keyboard for anyone spending significant time typing. It's a solid investment in your work comfort and overall hand health. If you're on the fence about purchasing, I highly recommend giving it a go. As someone sat at a keyboard all day writing and programming I have tried many different keyboards with both standard and ergonomic layouts. The Kinesis Advantage 2 LFQ (Low-Force, Quiet) keyboard is the best so far. The biggest selling point for this keyboard is its ergonomics. The Kinesis Advantage 2 LF features a key well design that comfortably accommodates your hands and fingers in their natural resting position, which drastically reduces the strain typically associated with long periods of typing. The key wells are split and angled for a more natural position for your arms, wrists and hands. Additionally, the keys are highly responsive and don't require much force to activate, leading to reduced hand fatigue and a more enjoyable typing experience. One feature this keyboard has that the newer 360 models lack is a piezo speaker. This speaker creates a key click sound on key actuation so you can hear when the key is activated. It's a small detail but helps to avoid "bottoming out" the keys which is a common cause of pain in your fingers from typing. I bought this keyboard because I suffer from RSI, it's not a cheap keyboard but for me the keyboard enables me to keep working pain free. If you are suffering from RSI do seek expert advice though, RSI is a catch all name for a variety of different symptoms with different causes, what works for some may not work for others. The keycap profiles on the Advantage 2 is fantastic with the home row being a different shape so your fingers can quickly recognise where they are on the keyboard without looking. Sadly these keys are made of ABS plastic, giving them a sticky feel. They are pretty thin and wear out quickly getting a very smooth and shiny texture. You can buy replacement PBT keycaps direct from Kinesis, they aren't quite the same profile as the originals but they do feel nicer to type on and should not wear out. The keyboard sounds very hollow which is a real shame, I feel kinesis could have improved on this and with the Cherry Red silent switches it could have been a very quiet keyboard. There are various discussions online on how best to reduce the sound on these keyboards, I personally haven't tried any of them yet though. The Advantage 2 also has powerful programmability with Kinesis own Smart Set system, offering the ability to customise every key to suit your specific needs. It's possible to program it from the keyboard itself switching key positions and recording macros which is useful if your IT department limit the control you have over your PC, but you can also mount the keyboard as a USB device by using a key combination where you can create more powerful customisations such as "mod tap" keys where if you tap the key it performs one action and if you hold the key it performs another. For example, on my keyboard I have the Caps Lock key mapped to Ctrl when it's held down and Esc when tapped. The keyboard has two layers per layout, but supports many custom layouts which you can activate using a keyboard shortcut. It takes a little while to adjust to having come from using a regular keyboard but I was back up to typing at around 90 wpm within a week. The instruction manual that comes with the keyboard provides some useful guidance. If you buy this keyboard, do make sure you read the instructions. This is by no means a cheap keyboard, but given it's programability, and potential to prevent repetitive strain injuries, I believe it's a worthwhile investment. The Kinesis Advantage 2 LF (KB600LFQ) is a phenomenal keyboard for anyone spending significant time typing. It's a solid investment in your work comfort and overall hand health. If you're on the fence about purchasing, I highly recommend giving it a go.

Avant, je n'arrivait pas de taper sur un clavier sans regarder les touches. Car avec dix doigts sur un clavier standard, mes mains commençait à faire mal au bout de dix minutes. Avec ce clavier ergonomique, je peux écrire pendant des heures sans douleur. Et ma vitesse d'écriture a plus que doublé ! Seul conseil : prendre la version silencieux (LF), car il est beaucoup moins bruyant que la version de base.

As a programmer, having on of these is a must. It's really good and helped me get rid of the pain in my hands

I was so excited when this product arrived at my house! I'm obsessed with good design and ergonomics, and this product did not disappoint. I was looking for something that would have absolute minimum impact on my fingers because I had tendonitis and pre-osteoarthritis from overwork. With this product, it feels very good to type, and I love the quiet cherry red keys. I read some reviews that said cherry red felt "mushy: but to me they feel awesome!! I love low-impact on my body. It warps my mind and makes me realize everything I've been doing wrong with typing. It also makes a fun parlor toy to show off to friends when they come over. None of us have ever seen anything like it before--even the nerdy tech guys in my family! I find the thumb keys the most difficult to relearn, though I know there are options to reprogram the way you want it--I haven't done that yet. I normally type 100-120 WPM on a traditional keyboard, but I'm super slow with this one as I get used to the curved keys and new thumb position keys. It's a great product for anyone who is serious about ergonomics--knowing as well that ergo is highly personal and it's important to find the right products that feel great and work for YOUR body and workspace setup.

The positioning of the thumb clusters is poorly designed and led to tendonitis in both of my thumbs. After prolonged use, I experienced significant discomfort and strain. If you’re prone to repetitive strain injuries, I’d strongly advise against this keyboard.
